BEARING FOR THE SPINDIJES OF FLIER SPINNING, DQUBLING, TWISTING, ANDLIKE MACHINES. 1

Application filed April 22, 1925. Serial No. 25,076.

To all whom it may concern.-

Be it known that I, ALFRED STELL, a subject of the King of GreatBritain, and resident of The Whins, Ingrow, Keighley, in the county ofYork, England, have invented a certain new and useful Improvement inBearings for the Spindles of Flier Spinning, Doubling, Twisting, andlike Machines, of which the following description, having reference tothe accompanying sheets of drawings, is a specification.

It relates to bearings for the spindles of flier spinning, doubling,twisting and like machines of the class wherein the driving wharle orpulley is situated at the upper end of the spindle and above the flier,and my said invention consists in so constructing the said drivingwharle or pulley and the sleeve or bearing which takes into and supportssame that I secure better lubrication for a longer period than ispossible with bearings as heretofore constructed.

In the accompanying sheet of drawings which illustrate my invention Fig.1 is a sectional elevation showing a rail A which extends from end toend of the machine and has the supporting brackets B fixed to it in theusual and well known manner, and my improved devices are shown mountedupon said bracket B.

Fig. 2 is a sectional plan, taken on line C. D. of Fig. l and show partshereinafter described.

In accordance with my invention I forinv the wharle or driving pulley 2so that it may be fixed upon the upper end of the spindle 3 asheretofore, but within the lower radial flange a: on said driving pulleyor wharle 2 I now form an annular space or cavity b so that lubricantmay be contained within said annular space 6 to which longi tudinalopenings 0 (through the body of the sleeve (5 of the bearings 4 for thespindle 3) lead to the u per end of said bearing 4.

In the upper radial flange f of the said wharle 2 I also form anotherannular space 9* (to contain more lubricant) and the upper wall 72, ofthis space is inclined downwardly towards the centre of the spindle 3 sothat its upper outer edge is higher than its inner edge. Thus thecentrifugal motions of the lubricant tend to cause same to rise to thehigher part of this space 9 and into contact with the inclined surface,

it so that as it is thereby prevented from flowing inwardly and risingover the flange 7 because the centrifugal actions on the lubricant causeit to flow down the incline surface it and back down the outer surfaceof the sleeve 03 to the lower end of the wharle 2. By these means allliability of any of the lubricant escaping and flowing away from thebearings is avoided. As stated I also form an annular space 6 in thelower flange a of the wharle 2 so that its upper covering surface p maybe inclined towards the spindle 3 as is the surface it and this I findto act as a prevention to the too great a rising of the lubricant withinthe cavity of the wharle 2.

The sleeve d of the bearing 4 taking within the wharle 2 as abovestated, has longitudinal openings 0 formed within its walls and saidsleeve 4 has also a cavity or well 25 formed at its upper end in orderthat the lubricant may be supplied to such cavity t so that same mayflow down through the openings 0 to fill the spaces within the wharle 2as above described.

The lubricating liquid as is well known is caused to flow or percolatebetween the rotary outer surface w of the spindle 3 and the inner wallof the sleeve 03 so that on rising from the space within the cavity inthe wharle 2 to the upper cavity t in the bearing 4, it then flows downthe openings 0 back to the cavity within the wharle 2, while by theinclined surfaces h and 39 acting as before described the overflowing orthrowing away of the liquid lubricant is prevented.

Such being the nature and object of my said invention what I claim is 1.The combination with the spindle of a spinning or similar machine, of awharle fixed upon the spindle and provided with an interior angularlubricant receiving cavity, the upper surface of which is in clineddownward toward the spindle receiving bore, and a relatively stationarysupporting sleeve surrounding the spindle and extending into said cavityin the wharle. said sleeve having a recess at its upper end and beingprovided with a plurality of ducts that extend from said recess throughthe end of the sleeve within the cavity in the wharle, for the purposedescribed.

2. The combination with the spindle of a spinning or similar machine, ofa wharle fixed upon the spindle and provided adjacent both ends withinterior annular cavilower cavity in the Wharle, said sleeve havties,both coinn'iunieating with the bore in ing a recess at its upper end andbeing prothe Wharle and having their upper surfaces vide'd with aplurality of ducts that extend inclined downward toward the axis of saidfrom said recess through the end of the bore, and urelutively stationarysupporting sleeve Within the Wharle, for the purpose sleeve surroundingthe spindle and extenddescribed.

ing through the bore in the Wharle into the ALFRED STELL.
